Psychrometric Chart

Pheinex, LLC
Interactive, graphical psychometric chart app. Allows you to create and manipulate charts and state points with the touch of your finger(s).

Add new state points by double tapping anywhere on the chart. Hold and drag existing state points to move them on the graph, with properties values updating live to aid you in setting them to the right value.

Works in both SI and IP units.

Processes that can be modeled include:

• An individual state point.
• Air mixing.

• Other processes by connecting state points.

Properties and energy change for connected points are calculated and displayed live.

Share your charts by exporting a PDF file or sending to an AirPrint device.
